Younger Patients Lose More Weight? Single Center 5-year Experience

Kamyar Hariri, MD, Matthew Dong, MD, MPH, Subhash Kini, Daniel Herron, MD, Gustavo Fernandez-Ranvier, MD, PhD. Garlock Division of Surgery, Icahn School of Medicine at Mount Sinai, New York

Background: Several previous studies have suggested a correlation between weight loss and age after bariatric surgery.

Objective: The aim of our study is to further address age as a preoperative factor to determine the amount of weight loss after bariatric surgery.

Materials and Methods: We performed a retrospective analysis of outcomes of a prospectively maintained database of 1,244 obese patients who underwent either sleeve gastrectomy (SG) or Roux-en-Y gastric bypass surgery (RYGB) at our hospital between 2011 and 2015. We analyzed the 3-month, 6-month, and 1-year postoperative percent total body weight loss (%TBWL) of obese patients who underwent bariatric surgery based on their preoperative age.

Results: The average age of patients included in the study was 45 years old with a range of 21–78 years. An inverse relationship between preoperative age and postoperative weight loss was observed. Younger patients achieved a higher %TBWL than older patients at the 3-month, 6-month, and 1-year postoperative follow-up. The average %TBWL for all patients at the 3-month, 6-month, and 1-year postoperative follow-up periods were 15.5%, 23.6%, and 28.9%, respectively. At the 1-year follow-up, for every decade increase in age (above the average age of 45), patients lost 4% less TBWL.

Conclusion: In our study, younger patients tend to lose a greater amount of %TBWL than older patients after bariatric surgery.

SAGES Response to NordICC Study Regarding Benefit of Screening Colonoscopies

The NordICC Study recently published in The New England Journal of Medicine and widely reported on by media outlets has raised questions regarding the benefit of screening colonoscopy in lowering the risk of colorectal cancer and cancer-related deaths among otherwise healthy and symptom-free men and women aged 55 to 64. Provocative headlines and commentaries have […]
